Title: Seals with low thermal expansion
Inventor: GAMARRA JOSE P
IPC: H02G3/06
Filed: 1993-08-06
Abstract: An improved sealing system. The sealing system provides for the use of a body (2) defining a cavity (4). The cavity is filled or substantially filled with a material (6) having a lower coefficient of thermal expansion than the body and, in some embodi-ments, a material that expands at low temperature. During low temperature operation, the body may shrink considerably, but the compressive force applied between two surfaces will not decrease appreciably due to the internal, low coefficient of thermal ex-pansion filler. Accordingly, the risk of seal failure at low temperature is substantially reduced.

Patent CA-2143930-A1 (CA)
Title: Frame synchronization method
Inventor: GEYWITZ KLAUS
IPC: H04B7/26
Filed: 1995-03-03
Abstract: The problem of pulse frame synchronization occurs for example in a telecommunications  system with cordless terminals operating according to the DECT standard.  To establish a radio connection between base station and a cordless terminal, the base station scans its radio cell in sequence with the available ten high-frequency carriers in the DECT frame rhythm.  In a multiple cell environment, the synchronization of all base stations belonging to a cordless telecommunications installation is necessary, to enable all base stations to scan the same frequency at the same time.  This is achieved by blanking the DECT multi-frame synchronization pulses.  The pulse gap is evaluated by error detection circuits which are present anyway, and used  for  the  PSCN  Primary  receiver  Scan  Number-synchronization.

Title: Web-Winding Process and Device
Inventor: DOERFEL WALTER
IPC: B65H18/26
Filed: 1994-08-24
Abstract: In order to be able to manufacture large-caliber reels of high quality in a twin drum reel-up, the king rolls (11) and (12) have different, diameters and are situated at different elevations. The main load of the reel is carried by the king roll (11), while the kind roll (12) contacts the reel (13) with the smallest possible nip pressure which just suffices for transferring the torque difference required for generating the desired winding tension of the reel. The king roll (12) may be lowered as the diameter of the reel increases, namely depending on the fact if the winding shaft (13A) is displaced along a predetermined line of motion (14; 15), preferably a linear vertical or slightly tilted line of motion. The winding device may comprise displacing elements (20) in order to displace king roll (12) axially parallel with respect to the king roll (11).   An articulated element (16) may allow detection of movements of the winding shaft (13A) and control of a displacing element (20) if the reel (13) is out of a given line of movement. An additional center drive which is made possible due to the aforementioned measures may additionally improve the winding result. A handling device (50) serves as a multifunction device for exchange of reels, in particular for the ejection of the reels, the clamping of the end of the web and the moving of the end of the web into the position for the next reel, as well as the separation of the finished reel from the web (1; 1'; 1"; ...).

IPC: C07C237/22
Filed: 1993-12-10
Abstract: Conjugates and methods of producing the conjugates and mixtures thereof are disclosed. Conjugates are comprised of an active polymer made up of monomer units selected from the group consisting of the monomer units of peptides and/or peptoids, and an encoding polymer comprised of encoding monomers wherein the encoding polymer corresponds to the active polymer, and a coupling moiety covalently coupled to the active polymer and the encoding polymer. In accordance with the synthesis methodology, mixtures of large numbers of conjugates are produced by providing a coupling moiety and covalent binding it to an active monomer and an encoding monomer.  Additional monomer units are added to the active monomer to create an active polymer and additional monomer units are added to the encoding monomer to produce an encoding polymer until the desired length is reached for the active polymer. Mixtures of conjugates attached to support bases can be used to assay a sample. The sample is brought into contact with the conjugates and a determination is made with respect to which active proteins bind to receptor sites within the sample. When active binding proteins are determined, the encoding polymer associated with the active polymer is sequenced, and by deduction, the sequence of the active polymer is determined.
